Description

Serrawettin W2 is a specialized biosurfactant and rhamnolipid compound, identified by CAS No. 140909-80-4, valued for its potent surface-active and emulsifying properties derived from microbial fermentation. This high-performance agent is critical for enhancing process efficiency and product performance in demanding industrial and formulation applications. It is an essential material for manufacturers in the agrochemical, personal care, and bioremediation sectors seeking effective, biodegradable alternatives to synthetic surfactants.

Application

• As a key emulsifying and dispersing agent in the formulation of agricultural pesticides, herbicides, and fungicides.
• As a foaming and wetting agent in the production of high-performance cleaning and detergent products.
• As a bio-based surfactant in cosmetic and personal care formulations, such as shampoos and skin cleansers.
• In enhanced oil recovery (EOR) and petroleum industry applications for reducing surface tension.
• For bioremediation processes to facilitate the degradation of hydrophobic environmental contaminants.
• As a stabilizing agent in the food processing industry (where compliant grades are available).
• In pharmaceutical research and development for drug delivery systems.
• For industrial biocontrol and antimicrobial surface treatments.

Quality Control

Our Serrawettin W2 is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC for assay and purity determination, to meet the specifications required for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and microbiological load is provided with each shipment to guarantee compliance with your quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
